The Correction of Slit-Width Errors

Abstract

The original purpose of this investigation was to explore the possibility of providing a spectrophotometer with automatic means for correcting the error that results when a continuous source is used with a monochromator having slits of finite width. In connection therewith, it was necessary to make what appears to be the first rigorous analysis of slit-width errors. The results of this analysis can be applied to the experimental determination of any functional relationship when the size of the “probe” is significant.
